WEATHER-STRIP.

Specification of Letters Patent.

Patented June 16, 1908.

Application tiled December 7, 1907. Serial No. 405,502.

To all whom 'it may concern.'

Be. it known that I, PETER L.- HEDBERG, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in VVeather-Strips, ofwhich the following is a specification.

'Ihis invention relates generally to metallic weather stri is, and whileit is more particularly inten ed to be used in connection with thepartin stops of window-sashes yet it is applicable or use on other partsof window-frames on the meeting rails of the upper and lower sashes andon door cases or frames; and it consists in certain peculiarities of theconstruction, novel arrangement, and operation of the various partsthereof, as will be hereinafter more fully set forthv and specificallyclaimed.

One of the objects of the invention is to provide a strip of theabove-named character that will be simple and inexpensive inconstruction, strong, durable and effective in operation, and of suchpeculiar formation as will allow of being readily and quickly a plied tothe structure so as to prevent ratt e and afford means to shut out dust,rain or wind. n

Other objects and advantages of the inven` tion will be disclosed in thesubjoined description and explanation.

In order to enable others skilled in the art to which my inventionpertains, to make and use the same, I will now proceed to describe it,referring to the accompanying drawing, in which- Figure 1 is a plan viewpartly in section and partlyin elevation taken on line 1 1 of Fig. 2 ofa portion of a window-frame and the sashes thereof, showing weatherstrips embodying one form of the invention in place thereon; Fig. 2 isan inner side view partly in section and partly inelevation, showing theapplication of the weather strip to the meeting rails of the sashes, aswellas to other parts thereof; Fig. 3 is a plan sectional view of adoor-casing, showing the weather strip applied to its sides and base orsill; Figs. 4 to 8, inclusive, are enlarged end views of different formsof the strip.

Like numerals of reference, refer to corresponding parts throughout thedifferent views of the drawing.

The reference numeral 10 designates, as a whole, the Window-frame orcasing which is provided, as usual, on each of its sides with partingstops 11 and inner and outer stops 12 and 13, respectively, for theupper and lower sashes 14 and 15, respectively, which latter have theinner surfaces of the meeting rails 16 correspondingly beveled, asusual, and as is shown in Fig. 2.0i' the drawing.

As is well-known and as is shown in Fig. 1 the sides of the window-frameare usuall provided with vertical grooves 17 in whic the parting stops11 are located, and it is a well-known fact that by reason of theshrinkage of the wood these stops are often spaced a slight distancefrom the walls of the grooves4 17 sometimes on one of their sides onlyand again on both sides. At any rate, they rarely ever fit between thewalls of the grooves very closely or so snugly as to prevent theinsertion between one of said walls and the adjacent surface of theparting stop of a 1portion of my improved weather strip, whic consistsof a strip of resilient material 1 8, usually metal of any suitablelength, which is preferably slightly bowed in cross-section and is adated to be placed between one of the surfaces of) the parting sto and theadjacent wall of the groove 17 in tfie side of the window-casing whereit will be held preferably by frictional contact and on account of theresilienc afforded by the curved or bowed shape o the. strip. At asuitable distance from one of its edges the strip is formed with alongitudinal groove 19 adapted to receive a deflected longitudinalflange 20-on the lower portion of the leaf-spring 21 which'extends thefull length of the strip and which lie's between the sash and partingstop. `That portion of the leaf-spring 21 opposite the flange 20 thereonis connected to the body 18 of the strip by means of a loop shapedortion or bead 22 which is soformed as to e located at one side of theplane of the body 18 of the stri thus affording greater resiliency tothe lea 21 as will be a parent.

By reference to tie drawing and especially to Figs. 1, 3 and 4 thereofit will be seen and understood that the bent or bow of the body 18extends outwardly from the parting stop 11 so that when the ortion ofthe strip 18 opposite the part 22 1s placed in the groove 17 lof thewmdow-frame the parting stop may be forced in lace, thus causing the'strip to be firmly he d between the stop and provided on their surfacesadjacent to the sashes with one of the strips, which canv be securedthereto in any suitable manner, butv so that their springs 21 will restagainst the sashes while the body portion 18 ol each ol the strips willrest against the said stops, in which arrangement it will be observedthat lthe beads or loops l22 will be located to one the drawing, thusclosing. the space between said rails and reventing the passage of dust,rain and wln In F1g.13 of' the drawmg I have shown a l door-casing 23with weather stri s embodydetail in Fig. 4 of the drawing.

ingmy invention secured. to its si es and bottom, in which the bodyportions of the stri s are secured to the desired portions of tlliecasing in such a way that the looped or beaded portions oi' the stripswill be. resented towards the door 24,'so that when it is closed thesprings 21 will contact with the edges of the door thereby closing thespaces between it andits 'frame or casing.

In Fi s. 5, 6, 7 and S are shown modified forms oli)r the stri which Imay sometimes use and any one Iorm of which may be employed for theparting stops, inner and outer stops of the window-casing, the meetingrails of the sashes, or for door-frames, in substantially the samemanner as the construction above-described and. illustrated in In themodiiication shown in Fig. 5 the body portion 18 is slightly bowed as inthe other construction, but the groove 19 is omitted therefrom, and inthe construction shown in Fig. 6 the loop or bead is omitted, but withthis exce tion the construction is the same as that s own in' Fig. 4 andfirst above-described. In the While I have shown in Fig. 1 vof thedraw-I ing a weather strip constructed as illustrated in detail in' Fig.4 and as a plied to each side.

of the parting stop, as we as to each of the inner and outer stops ofthe window-casing, yet I- do not desire to be limited to thisconstruction or arrangement, as I may` use a an outer stops of thewindow-casing. further obvious that any one of the con-- structionsdisclosed may be employed on the strip on one side only of the partingstop, and sau formsgherein shown. And, vit is apparent that. I may ormay not use any of the weather embodying my invention on the-iiner t ismeeting'rails of the window-sashes or on the door-frame, and that 1nsome instances the longitudinal [lange 20 on the free edge of theleaf-spring 21. may be omitted without departing from thespirit oi theinvention. B y constructing the body of the strip with the longitudinalgroove 19, which may sometimes be embedded in a suitable groove in theparting or other stop as shown in Fig. 4, it is evident that saidconstruction and arrangement will permit of the strip being used'inquite a narrow space and that the groove 19 will receive the ange20-'when the saine is employed.

Having thusfully described my invention,

what I claim as new, and desire to secure by Letters-Patent, is- 1.' Aweather strip consisting o'l a narrow piece of resilient materialcomprising a body portion having at one of its edges a loop providedwith a leaf-s ring extending 'from said loop outwardly ani. toward theother edge of the body portion and provided at its l'ree edge with adeflected llange.

2. A weather strip consisting of a narrow piece of resilient materialcomprising a body portion having a longitudinal groove and a eat-springextending from one of the edges of the body portion and outwardlytherefrom and toward its other edge, said lealispring having at its freeedge a dellected lange to fit in said groove.

weather strip consisting of a narrow piece of resilient materialcomprising a bowed ody portion having a longitudinally extending grooveand a leaf-spring extending from one of the edges of the body portionoutwardly and toward its other edge, said spring having f at its treeedge a deflected ange to iit in said groove.

4. A weather strip consisting of a narrow piece of resilient materialcomprising a bowed ody ortion havin a longitudinal groove and a 0o atone o its edges extendingto one vside o the plane of the body portion,said loop having a leaf-spring provided at its free edge'with adeflected flange to lit in said groove.
